Crestron 3 Series Quick Start Manual

CP3/CP3N
3-Series Control System® Automated Processors
The Crestron® CP3 and CP3N are compact, rack-mountable 3-Series® automated control processors with numerous integrated control ports.
Featuring the 3-Series control engine, the CP3 and CP3N unify the disparate technologies in residential, commercial, and government buildings
so that they can communicate and work together intelligently. The CP3N also supports the Crestron Control Subnet, which is an isolated gigabit
Ethernet network dedicated exclusively to Crestron devices.
NOTE: The CP3 and CP3N are functionally similar. For simplicity within this guide, the term "control system" is used to refer to both the CP3 and
CP3N unless otherwise noted.

Install the Device
The control system may be mounted into a rack or placed onto a flat surface.
Mount into a Rack
The control system occupies 1U of rack space. Use a #1 Phillips screwdriver to remove the required screws from the control system assembly (shown
in the illustration below), and then attach the two included rack ears with the removed screws. Mount the control system into the rack with four
mounting screws (not included).
Place onto a Flat Surface
When the control system is placed onto a flat surface or stacked with other equipment, attach the four included feet near the corners on the
underside of the control system.

Observe the following when connecting the control system:
4
• Use Crestron power supplies for Crestron equipment.
1
• The control system can be powered with the included 24 VDC power supply or via Cresnet® network power with the NET 4-pin terminal block
port.
4
• The included cables may not be extended.
1
• Connect the chassis ground lug to a known earth ground circuit (for example, building steel) to ensure that the control system is grounded
1
properly.
• Apply power after all connections have been made.

1. RS-422 transmit and receive are balanced signals that require two lines plus a ground in
each direction. RXD+ and TXD+ should idle high (going low at start of data transmission).
RXD- and TXD- should idle low (going high at start of data transmission). If necessary,
RXD+/RXD- and TXD+/TXD- may be swapped to maintain correct signal levels.
2. A ground terminal connection is recommended but not required.
Connect the Control Subnet (CP3N Only)
The CP3N has a dedicated Control Subnet that is used for communication between the control system and Crestron Ethernet devices without
interference from other traffic on the network.
NOTE: Do not connect the CONTROL SUBNET port to the LAN. The CONTROL SUBNET port must only be connected to Crestron Ethernet devices.
For more information on using the Control Subnet, refer to the 3-Series Control System Reference Guide (Doc. 7150) at
www.crestron.com/manuals.
